Here’s one from the rumor mill: Facebook may be acquiring a San Francisco-based social media company in the type of “talent acquisition” transaction that has become the trademark of the social web giant.

This rumor falls under the same category as the Zuckerberg $1 billion Mexican meal story (which shall henceforth be referred to as “TacoTip”): an item that could turn out to be interesting, or it could turn out to be nothing at all.

A reader told us that he overheard a conversation in his San Francisco-based dentist’s office between a patient and the receptionist. The patient told the receptionist that her social media company was being acquired by Facebook, but only the employees were being acquired and not the company itself. The reader was under the assumption that the patient’s company is based in San Francisco.

Who do you think Facebook is acquiring now? Tell us in the comments below.
